DIE non FORMING AXLES.

Application filed December 20, 1911'. Serial No. 667,006.

such as will enable others skilled in the art to which it pertains to make and use the same, reference bein had to the accompanying drawings, whic1 form a part of this specification.

My invention relates to an apparatus for a preliu'iinary forming of the material for the front axles of automobiles, and an object of my improvements is to provide for forming the ends in improved dies. I accomplish this object by the apparatus illustrated in the accompanying drawings, in which,

Figure 1, is one half of a die in which the axles are formed by punches 18 and 1941s shown. Fig. 2, is a view similar to Fig. 1, the punches and movable die being omitted. Fig. 3, is an end view looking from the right of Fig. 2. Fig. 4;, is a plan view of one half of the movable. die. Fig. 5, is an elevation of the part shown in Fig. 4, 10010 ing from the right of said figure. Fig. 6,

shows a part of the bar from which the axle is to be formed, the end being partly shaped as by the first operation. Fig. 7, is a view of the same part after being finished in the Fig. S, is a section on the line 88 Fig. 7 looking-from the right of the section line.

The end of the bar A is first formed as shown at B in Fig. 6 in one die, and then in a second die and, preferably, after reheating formed into the completed shape shown in Fig. 7. During the latter operation the metal isthickened and formed into the wedge shape shown at D Fig. 7, as a preliminary operation to forming the pad. In Figs-1 to 5 inclusive, only half of the part represented is shown (with the excepbeing precisely the same, or complementary.

1, is the main body of the die, this is formed with a groove 10 adapted to receive tlfe bar A from which the axle is to be formed. The groove 10 has an enlargement groove 13 into which the bar A may pass, said groove being extended laterally in both directions to form a cavity or socket for re ceiving the sliding die 2. Said cavity or socket opens in the right hand surface of the main body 1 of the die. There is a liner 8 placed along the bottom of said cavity upon The sides of which liner the die 2 moves. said cavity are undercut to form tracks or guides for the movable die, which is formed to said undercut portion at its edges.

7, is a lug extending from the main body 1 of the die and forming an adjustable stop to limit the motion of the movable die toward the right, as shown in the figures.

12, is a groove in the surface of the movable die 2 and adapted to come in line with andform an extension of the groove 13 in the main body 1 of the die. The groove 12 is enlarged toward its right hand end and opens through the right hand vertical surface of the movable die 2.

The inner bounding faces of the enlarged portion of the groove 12 are shaped to the contour of the inner surface of the fork C of the axle.

17, are pins or protuberances rising slightly from the bounding surface of the groove 12. The groove 12 at its left hand end is formed to the wedge shape half of the part I), and the groove 13 at its right hand end is shaped to form the other half, as inclicated by the reference letter E.

15, indicates wearing plates.

'19, is a punch having its left hand end the fork C of the axle- 5, 5 are stop pins removably placed in cavities fo-r that purpose in the body 1 of the die to form rests for the left hand ends of the spring 4. 6, 6 are similar stop-pins adapted to be inserted in cavities in the inner surface of the sliding die 2.

4-, 4 are compression springs, which act to force the sliding die 2 toward the right hand end of its-stroke, as shown in Fig. 1,

shaped to form the right hand surface of .thus leaving a space 16 between the left hand surface of the movable die 2 and the inner bounding surface of the-enlargement of the groove 13.

.Oil is supplied to the wearing surface of the die and' its socket through passages H, H.

The following is the mode otl f ormiug the axle and the operation of the above described apparatus. The bar A from which the axle is to be formed is first placed inthe groove 10. Enough of the metal of the bar. A comes into the enlargement to form the part B (Fig. (3) on the end of said bar, of course there the usual stop, "which it is not necessary to show properly position the bar A in a longitudinal direction. The punch 8 which is chainitered oli' in the direction to Which it is desired to force the metal in the shape shown. at G", Fig. l, is then forced into the enlargement 9 lorntring the part 13. The bar it having its end thus formed is then removed, reheated and placed in the grooves 12 and 13, the two parts of the dies being forced togetl'ier press the protuberances l7 into the metal of the bar to secure it longitudinally in the groove 12 of the movable die 2. The punch 15] is then forced into the enlarg ment of the groove 12, its inner end shaping the right hand surface of the fork C, as shown in Fig. l, and pressing the movable die' toward the left, thus expanding the metal of the bar A, which is between the ends of the grooves 13 and 12 into the and. shaping the pad .1). The end of the axle thus formed The bar A shaped toward each end as above described, is then ready to he made into the completed product. The dies may be kept cool with \vateifand the lubrication maintained.

lVhat ll claim is:-

A die body having a groove at one end adapted to receive a bar, a die block longitudinally movable in aconcavity in said die body and in line with the groove therein, said die block having a ciintinuationof said groove with an enlargementin its end 0ppo site the fixed groove in said die body and adapted to register with said groove, said die block having an enlargement of the groove at its opposite end, an upsetting punch adapted to enter said enlargement and term the end ot'a bar located in said grooves and also causing said die block to move and upset Said bar in the enlargement at its point of junction with the die body, substantially as described.

In testimony whereof, I sign this specification in the presence of two Witnesses.
